Sheep and cattle grazing alternately: Nematode parasitism and pasture decontamination
(2008-03-01)
Three grazing management systems were compared to examine pasture decontamination of gastrointestinal nematode parasites (GIN) of sheep (Ovies aries) and cattle (Bos taurus). They consisted of sheep and cattle grazing ...
Semen variables of sheep (Ovis aries) experimentally infected with Toxoplasma gondii
(2009-04-01)
The influence of Toxoplasma gondii on semen variables and sperm morphology of sheep was evaluated in eight reproductive males distributed into three experimental groups: GI, three sheep inoculated with 2.0 × 105 of P strain ...
Sexual transmission of Toxoplasma gondii in sheep
(2013-07-01)
Male sheep of reproductive age were distributed into three groups: GI, a sheep inoculated (oral) with 2.0×105 oocysts of the P strain of Toxoplasma gondii; GII, a sheep infected (subcutaneous) with 1.0×106 tachyzoites of ...
Efeito de três espécies de gramíneas forrageiras sobre a estrutura da pastagem e distribuição vertical de larvas infectantes de nematódeos gastrintestinais de ovinos
(2012-04-01)
The knowledge of interaction between infective larvae setting and the type of grass is important to epidemiological studies and the control of gastrointestinal nematodes in sheep. The objective of this work was to evaluate ...

Biological control of sheep parasite nematodes by nematode-trapping fungi: In vitro activity and after passage through the gastrointestinal tract
(2005-07-01)
The main method used for the control of gastrointestinal nematodes in sheep production is the application of chemotherapeutic agents, which often lead to the selection of parasites resistant to given active principles. ...
